1 Claim.

This invention relates to a work table.

An object of the invention is to provide a work table of the character described specially designed for use in wrapping articleswith a thin wrapper.

A particular object is to provide a work table of the character described designed to be used for wrapping packages of coffee or other similar articles.

A further object is to provide a work table having electrical heaters arranged accessible to the operator and over which the folds of the wrapping material may be passed after the article has been wrapped whereby the wrapping material will be sealed about the wrapped article.

It is a further object of the invention to provide, in a work table, supporting means for a roll of wrapping material with a hood or shield about the wrapping material so as to protect the thin Wrapping material against being dislocated by currents of air from fans or other sources.

A still further object is to provide in a device of the character described cutting blades arranged to cooperate to cut wrapping material as it is unwound from the roll, said blades being so arranged that workmen operating the device will not be liable to be cut or injured by said blades.

With the above and other objects in View, the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawing, wherein:

Figure 1 shows a plan view of the table.

Figure 2 shows a fragmentary front elevation.

Figure 3 shows a vertical sectional View taken on the line 3-3 of Figure 2.

Figure 4 shows an enlarged fragmentary sectional view showing the cutting blades, and,

Figure 5 shows a perspective view of the wrapped article.

Referring now more particularly to the drawing wherein like numerals of reference designate similar parts in each of the figures, the numeral l designates the top of the table which is mounted on suitable supporting legs 2. The table top has a smooth plane work surface.

Upstanding from the rear portion of the table there are the standards 3, 3, whose upper ends are connected by the cross-member A roll 5 of thin wrapping material such as Wrapping paper, or the like, is wound upon a mandrel 6, and the ends of this mandrel are reduced and rotate in suitable bearings l in the standards 3.

The free end of the paper may be drawn through a suitable transverse guide 8 secured on the table and in front of this guide there is a slot 9 over which the wrapping material passes as it is being cut into sheets of the required dimensions.

There is a blade Ill arranged to work through the slot 5. This blade is pivoted at one end on the pivot liia and its other end is connected to the vertical link H which extends downwardly through the table and whose lower end is pivotally connected to the inner end of the pedal l2, said pedal being hinged at its outer end to a lengthwise bar It. The blade iii is normally held elevated by the pull-springs it, Hi, whose lower ends are connected to the link H, and whose upper ends are attached to the underside of the table.

There is a stationary blade l5 which is fastened within the slot 9 and which is of a length slightly greater than the width of the strip of material to be cut. The upper margin of the blade I5 is located slightly beneath the surface of the table and the stationary blade is arranged to cooperate with the movable blade to shear the paper or wrapping material passing between the blades. There is a coil spring it attached at one end to the free end of the blade iii, and at its other end to one of the standards 3, and the tension of this spring holds the movable blade H) closely against the stationary blade i5. The blade i5 is located somewhat beneath the surface of the table so that the hand of the operator will not be injured should the movable blade contact therewith upon the downward movement of the last-mentioned blade.

There is a shield i'l whose upper margin is secured to the cross-member t and this shield curves rearwardly and downwardly and has its lower margin attached to the top of the table, thus forming a hood about the wrapping material so that said wrapping material will be protected in a large measure from air currents generated by electric fans in the building, or coming from any othersource. This protection is necessary for the reason that the wrapping material is very thin and light and would become disarranged or torn if exposed to strong air currents.

In use, the free end of the wrapping material is drawn forwardly until it engages the stop l8 at the front margin of the table, said material passing through the guide 8 and over the slot 9. The pedal I2 is then depressed by the operator, bringing the blade Ill into cooperative relation with the blade i5 and thus shearing 55 the wrapping material and separating a section the required size. The cut-off section is then wrapped about the article to be Wrapped and folded longitudinally forming the fold l9 and this fold is passed along over the electrical heater 20 on the top of the table. The wrapping material is of such nature that the heat will cause the overlapped portions of the paper or wrapping material to adhere together. The projecting ends of the wrapping material will then be folded at the ends of the wrapped article forming the folds 2! which are passed over the electrical heater22 now considered to be preferred forms of the invention by way of illustration only, while the broad principle of the invention will be defined by the appended claim.

What I claim is:

A paper feeding and cutting machine comprising a Work table having a slot, means for supporting a roll of wrapping paper on the table, a brake formed to act on the front of the roll, a sheet-like hood behind the roll extending from the table upwardly and over the roll, a paper guide mounted on the table, cutting means comprising a movable and a stationary blade, said stationary blade being positioned in said slot, with its upper edge located below the surface of the table, a treadle, said movable blade having one end pivotally mounted on the table and the other end, connected to the treadle, said treadle being adapted to raise and lower the movable blade into and out of cutting relationship with the stationary blade and means connected to the treadle to yieldably maintain said movable blade out of said cutting relationship.
